HideShow resource information
What is the formula for average speed?
average speed = distance / time
1 of 7
Define instantaneous speed
The speed of a car at a certain point in time
2 of 7
What is the formula for distance?
(u+v)t / 2
3 of 7
What does the increasing the speed mean?
Increasing the distance travelled in the same time, reduces the time needed to cover the same distance
4 of 7
In a distance time graph, what does the gradient tell you?
About the speed of the object. A steeper gradient means a higher speed
5 of 7
In a distance time graph, what does a straight line indicate?
That the speed is constant
6 of 7
In a distance time graph, what does a curved line indicate?
That the speed is changing
